2 main reactions in photosynthesis?
|
light dependent & light independent (calvin cycle)
|
|
equation for photosynthesis?
|
6 CO2 + 6 H2O + light --> 1 glucose + 6 O2
|
|
This molecule donates electrons to photosystem 2?
|
water (through photolysis)
|
|
where photosynthesis occurs?
|
chloroplast
|
|
light absorbing pigment molecule?
|
chlorophyll
|
|
Final electron acceptor after photosystem 1 in light reaction?
|
NADP
|
|
Reaction the produces ATP in photosynthesis?
|
light reaction (ETC in between P2 & P1)
|
|
3 process in Calvin cycle
|
carbon fixation, reduction & sugar production, regeneration of RuBP.
|
|
enzyme responsible for CO2 fixation?
|
rubisco
|
|
ATP produce in light reactions is used in this reaction?
|
Calvin cycle
|
|
Explains why plants are green?
|
chlorophyll reflects green light and absorbs blues & reds? Thus most photosynthetic activity at these ends of the spectrum.
|
|
During fixation, CO2 combines with RuBP to form this?
|
3PG
|
|
3PG is reduced to form
|
G3P
|
|
Where light reactions take place in chloroplast?
|
thylakoids
|
|
Where calvin cycle takes place in chloroplast?
|
stroma
|
|
production of ATP using energy from sunlight is called?
|
photophosphorylation
|
|
Describes when rubisco adds O2 to RuBP instead of CO2. Causes plant inefficiency.
|
photorespiration
|
|
2 adaptations plants have evolved to minimize photorespiration.
|
C4 and CAM
|
|
These plants change the location of where carbon fixation occurs (from mesophyll cells to bundle sheath)>
|
C4
|
|
These plants improve photorespiration by timing. CO2 is fixed at night when stomata are open. Rest of Calvin cycle occurs during day.
|
CAM
|
|
Energy is transformed in photosynthesis from _____________ to _____________.
|
light to chemical.
